Kaempferol and kaempferide suppressed lipid accumulation in OA-induced HepG2 cells. HepG2 cells were incubated with different concentrations of kaempferol or kaempferide in the presence of 0.5 mM OA for 48 h. (a) Oil red O staining in the cultured HepG2 cells. (b) Visualization of intracellular lipid droplets in HepG2 cells under microscope (100× magnification). (c) Quantification of intracellular TG contents in HepG2 cells. Data were expressed as mean ± SD of three independent experiments (n = 3). ## p < 0.01, compared with vehicle-treated control cells (Con); ** p < 0.01, compared with OA-treated cells (OA).
